Foundations Walls
One of the biggest issues with foundation or retaining walls are the vast majority of foundation problems is water. Wet soil beneath a foundation can swell or lose strength.
Undertile
Hyperdesmo is an excellent option for applying under tiles, such as in a wet room. The liquid seals the substrate, making it fully waterproof.
Over Tile
A common source of balcony leaks is improper waterproofing, leading to issues like incorrect application, damage, or blocked drainage, which can result in flooding.
Green Roofs
A green roof contributes to the sustainability of a building while it offers many benefits to the urban environments.
Flat Concrete Roof
Waterproofing a new flat concrete roof can be challenging. Concrete tends to expand or contract in hot or cold weather, over time which causes it to crack especially in the first 18-24 months of its life.
Car Parks
Car parks above the shopping area are becoming the norm due to restricted space available.
Sealants
HYPERDESMO® boast a variety of different sealants. Our sealants combine the technology of polyurethane and silylated polyurethanes.
Planter Boxes
Planters offer an elegant way to display flowers, but stone or brick planters often leak at seams and joints, leading to water seepage that can damage the slab and corrode reinforcement.
