What we deliver and which problem we solve
What we deliver
Infra Remonti EOOD specializes in comprehensive repair of terraces and balconies, approaching each site as a complex engineering system, not a cosmetic task. Our scope of work includes full diagnosis of the problem, removal of all compromised layers down to a sound base, structural restoration of the reinforced concrete slab, anti-corrosion treatment of the rebar, creation of a new slope layer with a perfect gradient of 1.5-2%, application of multi-component elastic waterproofing systems, and installation of a finishing layer. Our teams are certified to work with systems from leading manufacturers such as Sika, Mapei, and Baumit. We primarily operate in Varna and Burgas, where the specific maritime climate requires special materials and technologies for protection against salt corrosion, but we also undertake large-scale projects in Plovdiv and Sofia, considering large temperature amplitudes and freeze-thaw cycles. We have specialized equipment, including Hilti breakers for controlled demolition, rebar detectors, thermographic cameras for detecting hidden leaks, and laser levels for precise slope setting. Our approach is to solve the problem at its root, ensuring long-term structural stability and complete watertightness.
Which problem we solve
The main problem we solve is the progressive deterioration of the terrace caused by water penetration. This manifests in many ways: leaks into the sub-roof space or the room below the terrace, dampness and mold on walls and ceilings, crumbling plaster and falling concrete pieces from the balcony edge, which pose a direct danger. A common but initially invisible problem is rebar corrosion. Penetrating moisture causes rusting, where the volume of steel expands up to 7 times, creating enormous internal stress that literally explodes the concrete from within. This leads to cracks, spalling, and ultimately compromises the load-bearing capacity of the entire cantilever structure. Many companies only offer re-tiling or applying a new waterproofing layer on top, which is an absolutely wrong approach. This 'solution' merely seals moisture into the slab, accelerating corrosion and destruction. We prevent these catastrophic scenarios by completely removing old compromised layers and restoring the structure from scratch. We stop leaks, eliminate the risk of falling elements, restore structural integrity, and provide security and peace of mind for decades to come, backed by our 15-year warranty.

What does a complete terrace repair include?
Our process is comprehensive and designed to eliminate all potential weak points in your terrace's construction.
Full diagnostic with equipment
We use non-destructive methods such as thermographic analysis to locate hidden leaks and thermal bridges, as well as moisture meters for accurate measurement of base saturation. This initial step allows us to determine the exact scope of necessary repair work and avoid unnecessary costs by focusing only on problem areas.
Complete demolition down to the load-bearing slab
We remove all existing layers – tiles, old waterproofing, compromised screed for slope. We use professional Hilti breakers with controlled power to reach the sound reinforced concrete slab without causing vibratory damage to the structure. This is the only way to ensure that the new system will be laid on a clean and stable base.
Inspection and anti-corrosion treatment of rebar
After exposing the concrete slab, we inspect the condition of the rebar mesh. All corroded areas are mechanically cleaned to bright metal (Sa 2.5 standard), then treated with specialized two-component epoxy or polymer-cement anti-corrosion passivation coatings such as Sika MonoTop-910 N, which stop the rusting process and restore the alkaline protection of the steel.
Structural concrete restoration
All cavities, cracks, and damaged areas on the concrete slab are filled and restored using special repair mortars of class R4 (according to EN 1504-3), such as Sika MonoTop-412 NFG. These materials have a compressive strength of over 45 MPa, low shrinkage, and excellent adhesion to old concrete, fully restoring the monolithic nature and load-bearing capacity of the structure.
Construction of a new screed for slope
We form a new reinforced screed with a minimum thickness of 3-4 cm, which is precisely leveled with a laser to ensure a mandatory slope of at least 1.5% to 2% towards the drainage elements (siphons, gutters). The correct slope is critical to prevent water retention on the surface and eliminate the risk of future leaks.
Installation of drainage elements and profiles
We install new, high-quality floor siphons with a waterproofing flange and seal their connection to the base. Along the outer edge of the terrace, we install system aluminum or steel drip profiles (drip edges) that direct water away from the balcony edge, preventing backflow and subsequent destruction of the plaster.
Application of elastic waterproofing system
We apply two coats of highly elastic two-component polymer-cement waterproofing (e.g., Mapei Mapelastic or SikaLastic-152), with a total thickness of 2-3 mm. An alkali-resistant fiberglass mesh is embedded between the two layers for additional strength and crack-bridging ability. All corners and connections are treated with additional sealing tapes.
Application of decoupling membrane (optional)
For large areas or in regions with extreme temperatures (Plovdiv, Sofia), we highly recommend the application of a decoupling membrane such as Schlüter-DITRA. It absorbs stresses from thermal expansion between the substrate and the covering, preventing cracking of tiles and joints and providing an additional waterproofing layer.
Installation of frost-resistant flooring
We lay porcelain stoneware tiles with a wear resistance class of at least PEI IV and proven frost resistance. We use a highly elastic adhesive of class C2TES1 (e.g., Ceresit CM 17), which is applied both to the substrate and to the back of the tile (double-buttering) for 100% coverage and absence of voids where water could collect.
Elastic grouting and sealing
Grouting is performed with elastic, hydrophobic grouting compounds of class CG2 WA. All perimeter and expansion joints, as well as connections with joinery and walls, are sealed with a permanently elastic polyurethane or MS-polymer sealant. This ensures the system's flexibility and hermetic sealing of all critical details.
Our Proven 8-Step Process
We follow a strict technological sequence that guarantees quality and durability of the repair.
- 1
Step 1: Free Inspection and Diagnosis
Our technical manager visits the site to perform a visual inspection and instrumental diagnosis. We discuss the problems and your requirements, then prepare a detailed quantity-value estimate and technical proposal. This first step is completely free and does not oblige you to a contract.
- 2
Step 2: Clearing and Demolition
After signing the contract, we secure the perimeter and begin removing all layers down to a sound base. We work with professional equipment to minimize dust and noise. All construction waste is collected in bags and transported to a specialized landfill, leaving the site completely clean.
- 3
Step 3: Base Preparation and Repair
The base is cleaned with a high-pressure water jet. Corroded rebar is treated with anti-corrosion coatings. All concrete defects are repaired with specialized R4 repair mortars. This step restores structural integrity and prepares a perfect base for subsequent layers.
- 4
Step 4: Slope Formation
We apply a new reinforced screed for slope, using a laser level to achieve a precise and uniform gradient of 1.5-2% towards the siphons. The screed is left to cure for a minimum of 72 hours before subsequent operations to minimize the risk of shrinkage cracks.
- 5
Step 5: Waterproofing Application
We apply the first layer of polymer-cement waterproofing, into which we 'embed' an alkali-resistant mesh and sealing tapes in the corners. After drying (about 4-6 hours), we apply a second, finishing layer perpendicular to the first. The result is a seamless, elastic membrane 2-3 mm thick, completely waterproof.
- 6
Step 6: 24-hour Water Test
Before laying the final flooring, we perform a mandatory 24-hour water test. We block the siphons and flood the entire terrace with a few centimeters of water. This is the surest way to 100% verify the success of the waterproofing work and ensure there are no leaks.
- 7
Step 7: Flooring and Grouting
After a successful water test, we proceed with tiling porcelain stoneware slabs with elastic C2TES1 adhesive. Each tile is precisely leveled. We leave technological joints of 3-5 mm. After a minimum of 24 hours, we grout with an elastic, water-repellent grouting compound. This ensures not only aesthetics but also the durability of the flooring.
- 8
Step 8: Final Sealing and Handover
All corner and expansion joints are filled with permanently elastic PU sealant. We clean the site and perform a final inspection with the client. We issue a handover protocol and a written 15-year warranty for the construction works performed. Your terrace is ready for use.

This is a single-component, fiber-reinforced cementitious repair mortar that meets the highest class R4 according to EN 1504-3. We use it for repairing large defects and structural strengthening of the concrete slab. With a compressive strength of >55 MPa after 28 days and excellent adhesion, it restores the monolithic nature of the structure and guarantees long-term durability, even under harsh operating conditions. Its low shrinkage prevents cracking.
Elastic Waterproofing: Mapei Mapelastic
A two-component, highly elastic cementitious waterproofing that remains flexible even at -20°C. It has crack-bridging ability up to 2.5 mm. It is applied in two layers with a total thickness of 2 mm, forming a strong, seamless membrane that is completely watertight under pressure up to 1.5 bar. Certified according to EN 1504-2 and EN 14891. The excellent choice for terraces and balconies exposed to intense atmospheric influences and temperature changes.
Decoupling Membrane: Schlüter®-DITRA 25
A polyethylene membrane with an embossed structure that performs five functions: decoupling, waterproofing, load distribution, vapor equalization, and anchoring. It is laid between the screed and the tiles to neutralize stresses from differential movements. This effectively prevents cracking of tiles and joints – a common problem on large terraces and with sharp temperature changes, typical of the continental climate in Plovdiv and Sofia.
Tile Adhesive Class C2TES1: Ceresit CM 17 "Stop Dust"
A flexible tile adhesive that meets class C2TES1 according to EN 12004. "C2" means improved adhesion (>1 N/mm²), "T" - reduced slip, "E" - extended open time, and "S1" - high deformability. This makes it ideal for outdoor applications, for application over waterproofing, and for bonding large-format porcelain stoneware. The "Stop Dust" formula reduces dust generation during mixing by up to 90%, improving working conditions.
Anti-corrosion Protection: Sika MonoTop®-910 N
A single-component, polymer-modified cementitious mortar used both for anti-corrosion protection of rebar and as a bonding bridge between old and new concrete. It restores the alkaline environment around the steel, passivating it and stopping corrosion processes. Its adhesion to steel and concrete is over 2.0 MPa, which guarantees a perfect bond and collaborative work of old and new materials in the repaired structure.
