A minor leak today can turn into structural damage, mold growth, and expensive repairs within months. A hairline crack in a basement wall, a poorly sealed pipe penetration, a flat roof with no membrane – each one becomes a problem that gets worse over time. MC Bauchemie is a German construction chemicals manufacturer with over 50 years of experience solving exactly these problems.

Their waterproofing product range covers active leak sealing, surface coatings, sheet membranes, and cementitious systems. This blog breaks down the main categories so you can match the right solution to your project.

Why One Waterproofing Product Does Not Fit Every Situation

Waterproofing is not a single problem. An actively leaking basement crack needs a different solution from a new roof terrace that needs long-term moisture protection. A water tank has different requirements than a below-grade retaining wall.

MC Bauchemie builds its product range around this reality. Each product targets a specific scenario, substrate type, and performance requirement. Choosing the right one depends on where water is coming from, whether it is active or latent, and what access the site allows.

Injection Systems Stop Water From Inside the Structure

When water is actively entering through cracks or joints, surface coatings cannot solve the problem on their own. Injection technology works from within the structure, sealing pathways before water reaches the surface.

MC-Injekt GL-95 Seals Cracks in Concrete and Masonry

MC-Injekt GL-95 is a low-viscosity acrylate gel sealant injected directly into cracks with a width of 0.1 mm. It reacts to produce a swellable, elastic seal that holds even as the structure moves or moisture levels fluctuate.

Its reaction time runs up to 10 minutes and is adjustable, giving applicators control over how far the resin travels before setting. It carries DIBt approval for injection into soil and groundwater and meets German environmental agency standards for contact with potable water. Basements, retaining walls, and masonry structures with rising damp are its primary applications.

MC-Injekt 2300 Flow Handles Actively Running Water

MC-Injekt 2300 flow is a polyurethane injection resin that reacts on contact with water. It expands to fill the void and stops active water movement fast. The wetter the crack, the faster it sets.

Applicators use it in tunnels, underground shafts, manholes, and pipe penetrations where water is flowing under pressure. It works in conditions where other resins simply cannot cure properly.

Surface Coatings Protect Large Areas Quickly and Reliably

Polymer-Modified Coatings for Below-Grade Structures

MC Bauchemie’s polymer-modified waterproofing systems are designed for spray application across large surfaces. They adapt to uneven substrates and complex geometries, including protrusions, abutments, and light shafts that sheet membranes struggle to cover.

These systems suit basement slabs, retaining walls, and foundation waterproofing where coverage speed matters and site conditions are variable.

Expert Proof Reactive Sealants for Roofs and Terraces

The Expert Proof range is bitumen-free and fast. It becomes rain-resistant within a few hours and bears mechanical loads after 24 hours. That turnaround makes it practical for exposed roofs and terraces in occupied buildings where downtime needs to stay short.

It forms a continuous skin over the substrate with no joints or laps. Joints are the most common failure point in traditional sheet systems. Removing them removes the risk.

MC-Proof 4200 for High-Performance Industrial Applications

MC-Proof 4200 is a two-component spray-applied polyurea coating. It is solvent-free, cures within an hour, and delivers high resistance to abrasion, impact, chemicals, and UV exposure. It bonds to concrete and steel and produces a seamless, monolithic layer across the entire surface, including field joints.

Car parks, water treatment facilities, industrial floors, and exposed infrastructure are its typical applications. It requires professional spray equipment and trained applicators.

Membranes Deliver Reliable Protection Below Grade

MC-Nafuplan is a self-adhesive SBS-modified bitumen membrane that bonds fully to the substrate. It resists chlorides, sulfates, and ground salts, a relevant consideration for coastal and high-salinity ground conditions common across the UAE.

MC-Plan 120 IN is a 2mm PVC membrane for below-grade and exposed surfaces. Hot air welding creates a continuous, seamless layer at every joint. Its dual-tone design allows visual inspection of weld quality during installation, reducing the chance of defects passing undetected.

Dichtament DS2 Is a Practical Choice for Tanks and Masonry

Dichtament DS2 is a cementitious waterproof coating applied directly to concrete, brick, masonry, and plaster. It protects water tanks, roof slabs, basement walls, and foundations exposed to ground moisture, salt, and hydrostatic pressure. It works as both the waterproofing layer and the finished surface, keeping the system simple and the application cost manageable.

Frequently Asked Questions

What is the difference between injection resins and surface waterproofing coatings?

Injection resins seal from inside the structure. They go into cracks, joints, and voids through drilled packers, blocking water pathways within the concrete or masonry itself. Surface coatings go on the accessible face and stop moisture from reaching the substrate at all. Most remediation projects need both. The injection stops active leaks first. A surface coating then provides long-term protection once the structure is stable and dry.

Which MC Bauchemie product works best for below-grade structures in the UAE?

It depends on site conditions. For foundations in coastal or high-salinity ground, MC-Nafuplan membrane resists chlorides and sulfates well. For complex substrate shapes, polymer-modified spray coatings are easier to apply without leaving gaps. Where water is actively entering before other work can begin, MC-Injekt 2300 flow stops the leak first. Most projects combine two or more products rather than relying on a single system. The CretePro team can advise based on your specific substrate, groundwater conditions, and timeline.

Are MC Bauchemie waterproofing products suitable for potable water structures?

Several products in the range are approved for potable water contact. MC-Injekt GL-95 meets German environmental agency standards for sealants in contact with drinking water and carries DIBt approval for injection into soil and groundwater. Dichtament DS2 is commonly used for water tanks and treated water structures. Always check the product technical data sheet for the specific application and verify compliance with UAE local standards before specifying for potable water use.
