Liquid Rubber & Fiberglass Waterproofing in Malaga
Our flagship system: high-density liquid rubber reinforced with fiberglass mesh. A seamless, elastic, joint-free and fully walkable membrane — engineered to withstand the Costa del Sol climate.
The system
What Is Reinforced Rubber Waterproofing?
Reinforced waterproofing combines high-density liquid rubber with a fiberglass mesh that acts as a structural skeleton. The rubber is applied in successive coats, with the mesh embedded between them. The result is a seamless membrane — no joints, no overlaps, no failure points — creating a 100% watertight barrier.
Unlike applying a simple "waterproof paint", the fiberglass reinforcement provides mechanical strength and elasticity exceeding 400%. This means the membrane moves with the building's expansion and contraction without cracking — critical in Malaga where surface temperatures can vary by over 40 °C in a single day.
For expat property owners, this is particularly important: many villas and apartments on the Costa del Sol were built with traditional Spanish construction methods (thin terracotta tiles known as baldosín catalán over concrete). Our system works directly over these surfaces without any demolition.
Advantages
Why Reinforced Rubber Coating Is Superior
No demolition required
Applied directly over tiles, baldosín catalán or concrete. We never rip up your floor or generate demolition waste.
Elasticity >400%
Stretches and contracts with the structure without cracking. Withstands the extreme thermal movement of the Mediterranean climate.
Seamless membrane
No joints, no overlaps, no failure points. Water simply cannot find a way through, unlike bitumen felt.
Fully walkable
Mechanical resistance for normal pedestrian use. Use your terrace as normal once the system has cured.
Cold application
No blowtorch or open flame required. A safe process with no bituminous fumes or fire risk on your roof.
Multiple colours
Available in terracotta red, grey, reflective white and green. White reduces terrace temperature significantly in summer.
Comparison
Rubber + Fibre vs. Other Systems
| Feature | Rubber + Fibre (Soliva) | Bitumen felt | Sprayed polyurethane |
|---|---|---|---|
| Joints/Seams | Completely seamless | Overlapping seams (weak points) | Seamless but uneven |
| Application | Cold applied (safe) | Requires blowtorch (fire risk) | Heavy machinery needed |
| Elasticity | >400% | Low (cracks in heat) | Medium-High |
| Finish | Smooth, multiple colours | Black or grey only | Rough "popcorn" texture |
| Walkability | High (pedestrian traffic) | Limited | Requires additional layer |
| Demolition needed | No | Yes (remove existing floor) | Yes (surface preparation) |
Technical process
How We Apply the System Step by Step
Deep cleaning and preparation
We remove mould, dust, grease and remnants of previous treatments. Loose tiles and deep cracks are repaired and filled.
Treatment of critical points
Drains, expansion joints, skirting areas and wall junctions receive specific reinforcement before the general treatment.
Penetrating primer
A base coat that consolidates the substrate and ensures maximum adhesion of the rubber to the existing surface.
First rubber coat
A thick coat of high-density liquid rubber spread evenly across the entire surface.
Fiberglass mesh placement
While the first coat is still fresh, we embed and smooth the fiberglass mesh. This is the "secret" that prevents future cracking.
Cross-layered sealing coats
2-3 additional coats of rubber in alternating directions. The result: a seamless, joint-free, absolutely watertight mantle.
Frequently asked questions
About Rubber & Fiberglass Waterproofing
Can liquid rubber be applied over existing tiles?
Yes — this is one of the system's greatest advantages. It only requires thorough cleaning and an appropriate primer to ensure adhesion. We never remove a single tile.
How many coats of rubber are needed with the fiberglass?
We recommend a minimum of 3 generous coats (sandwich system) to ensure the mesh is fully embedded and the membrane is completely watertight.
Is the rubber and fiberglass coating walkable?
Yes. The fiberglass reinforcement provides mechanical resistance for normal pedestrian traffic. It is not suitable for vehicle traffic.
What is the difference between "rubber paint" and your system?
Rubber paint alone is a thin layer without structural reinforcement that cracks under thermal movement. Our system incorporates fiberglass mesh between the rubber coats, creating a far stronger and longer-lasting elastic armour.
What colours are available?
We offer terracotta red, grey, white and green. The reflective white is especially recommended in Malaga as it reduces the terrace surface temperature and can lower air conditioning costs.
