Berlin Wall and Raft Foundation Waterproofing
Waterproofing Berlin walls, a technique commonly used in urban construction, involves reinforcing and sealing temporary or permanent retaining walls. These walls, made of concrete panels driven into the ground and held by tie-backs, require waterproofing to protect adjacent structures from underground water and moisture.
Waterproofing can be achieved using membranes, special coatings or drainage systems to ensure the durability and safety of the structure and surrounding areas. HIZO has the expertise required for these complex applications.
Blindside Waterproofing Systems
Torch-Applied Blindside Waterproofing Membrane
The torch-applied blindside waterproofing membrane is a robust solution composed of modified bitumen and a composite reinforcement. Its surface is treated with sand, while its underside is covered with a detachable silicone film.
This membrane is specially designed for vertical waterproofing of Berlin walls. To ensure complete waterproofing, the plastic film and transverse overlaps must be torch-welded, either with a propane torch or an electric hot-air gun.
This system benefits from the exothermic reaction of curing concrete, which strengthens the adhesion between waterproofing membranes and structural concrete through superior chemical and mechanical bonding.
- Designed for Berlin walls
- Chemical and mechanical bond
- Sanded surface for adhesion
- Optimal vertical waterproofing
Blindside Liquid Membrane
The blindside liquid membrane is an elastomeric asphalt-based coating designed for commercial waterproofing in applications such as slabs, buried roofs, raft foundations on mud slabs, Berlin walls and complete tanking.
Resistant to shotcrete applications, this liquid membrane stands out for its versatility and cold spray application, forming a durable and seamless membrane. Compatible with a wide range of surfaces, it excels with its exceptional ability to expand and contract, allowing it to effectively resist all weather conditions.
- Cold spray application
- Resists shotcrete
- Seamless membrane
- Geotextile reinforcement possible
