Frequently Asked Questions About Bonus Proof Membrane
BONUS PROOF is a high-performance, polyester-felt waterproofing product used for single-sided wall, foundation, and deep foundation waterproofing without the need for protection concrete. It adheres fully to fresh concrete through elastomeric (SBS) additives with concrete pressure and hydration heat.1. How does Bonus Proof adhere to concrete?
Bonus Proof, thanks to its superior high-SBS formula, fully adheres to fresh concrete using the hydration heat that occurs during the concrete's drying process. Its self-adhesive seams ensure the creation of a seamless waterproofing system.
2. How reliable is the Bonus Proof waterproofing system without protection concrete or covering?
Bonus Proof membranes are elastomeric bituminous sheets, reinforced with high SBS content and capable of withstanding temperatures as low as -20°C. These sheets contain additives that allow for self-healing in case of punctures or impacts during application, preventing water leaks. As a result, Bonus Proof membranes are more reliable than alternative waterproofing membranes or coating systems.
3. How should Bonus Proof membranes be applied correctly?
Once the foundation's concrete surface is cleared of foreign materials, the membrane is laid in a staggered pattern along the length of the surface. Overlaps of 15 cm widthwise and 10 cm lengthwise are maintained. The overlapping areas and self-adhesive seams are lightly heated with a torch, and a 10-12 kg roller is used to press the seams. Once the seams have dried, the application of steel reinforcement can proceed.
4. How does Bonus Proof perform in deep foundations with high pressure?
Bonus Proof membranes, tested for high hydrostatic pressure by internationally accredited laboratories, have demonstrated superior performance in deep foundations where water pressure is high. These results are documented in the product's technical specifications. In case of water leaks after application, localized injections allow for quick repairs without needing to remove the entire membrane.
5. How does seawater or saltwater affect the performance of Bonus Proof membranes?
The average salinity of ocean water is about 3.5%, which translates to roughly 35 grams of dissolved salts (mainly sodium chloride ions Na+ and Cl-) per kilogram or liter of seawater. This amount is negligible and has no significant impact on the performance of Bonus Proof membranes.
