????Large Deck Over an Underground Car Park:
???? ???????????????? ???????????????????????? & ???????????????????????????????????????????????????? ????????????????????????????????????????
Our experienced surveyor recently visited this Bournemouth, mid-1970s purpose-built apartment complex comprising two 7-storey towers with a shared basement car park, to carry out a comprehensive inspection following reports of water ingress.
???? ???????????????????? ????????????????????????????????????????:
Water penetration was observed through the roof slab of the basement car park. The original deck was constructed using asphalt membranes, which are known to degrade under prolonged UV exposure. Over time, thermal expansion and contraction can lead to fatigue and cracking—especially at high-stress areas such as corners, structural junctions, and upstand details.
???? ???????????? ????????????????????????????:
It’s important to note that visible leaks on the underside of a concrete slab don’t always indicate the exact point of water entry. Water can migrate through construction joints, and movement joints before becoming visible below.
????️ ???????????????????????????????????????? ????????????????????????????????:
The basement structure consists of reinforced concrete downstand beams supporting a 150mm thick slab. The ground-bearing slab includes perimeter edge thickenings and reinforced concrete walls to retain surrounding ground levels. Our inspection also highlighted the need for upstand and concrete repairs in several areas.
We’re now working closely with the client to develop a robust waterproofing solution tailored to the unique challenges of this buried deck system.
????Semi-Basement Extension, Salisbury: Following our pre-construction waterproofing survey, our technicians are now on site installing a ???????????????? ???? ???????????????????????? ???????????????????? ???????????????????????????????? ???????????????????????? to protect the newly built semi-basement extension at this ???????????????????? ???????? ???????????????????????? property in Salisbury.
Although not a full basement, the structure still requires effective protection against water ingress to ensure it remains dry and habitable—fully compliant with ???????? ????????????????:???????????????? standards for below-ground waterproofing.
???? ???????????????????????????????? ???????????????????????????????? – Gravity-Fed System:
As part of our design, we offered the option of a sump and pump system to manage any potential water ingress. However, the client opted for a gravity-fed drainage solution, which is a passive system that relies on natural fall to direct water away from the structure.
This approach involves:
✅ ???????????????????????????????? ???????????????????????????????? integrated at the base of the cavity membrane system.
✅ ???????????????????????????????? ???????????????? ???????????????? ???????????? ???????????????? designed with sufficient fall to ensure continuous flow.
✅ ???? ????????????-???????????????????????? ???????????????????? fitted to prevent any risk of backflow from the external surface water system.
Gravity-fed systems are highly effective where site levels allow, offering a low-maintenance, energy-free solution for managing groundwater ingress.
We’re proud to support projects that combine modern construction with heritage sensitivity—delivering long-term protection and peace of mind.
