SERVICE ENTRY SEALING
WHY SEAL SERVICE ENTRIES?
A below ground structure needs to be waterproof if it is to protect its occupants from flooding. Therefore, it is important to consider penetrations through a waterproofing system and whether this poses a risk to the integrity of the system. In most cases, a below ground service entry will create a weak spot in the system design and so this must be addressed.
HOW TO SEAL A SERVICE ENTRY
The method of sealing a service entry must be chosen after considering the type of waterproofing system it is to work in conjunction with and the services that require sealing.
Methods may include the use of butyl rubber tapes or top hats to link cavity drainage membranes to pipework or the injection of resins or putty around cables. Our close relationships with our manufacturer suppliers enable us to select an appropriate method to suit any system or service.
