Balconies often suffer from direct exposure to heat and rain. Our waterproofing stops moisture intrusion and concrete damage with UV-stable coatings made for Leonay.
Kitchens and laundries exposed to dampness risk developing wood rot and mould. Our waterproofing service in Leonay includes underfloor and wall sealing to protect cabinetry and internal flooring.
Improperly sealed planter boxes can lead to serious leaks. Our planter box waterproofing uses root-resistant membranes to stop overflow and protect nearby walls from seepage.
Specialist care is needed to waterproof pools and decorative ponds effectively. In Leonay, we apply flexible, water-resistant coatings made for submerged environments.
