๐นLarge Deck Over an Underground Car Park:

Our experienced surveyor recently visitedย 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.
๐งย ๐๐๐๐๐ฒ ๐๐ฑ๐ฒ๐ป๐๐ถ๐ณ๐ถ๐ฒ๐ฑ:
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 crackingโespecially at high-stress areas such as corners, structural junctions, and upstand details.
๐ย ๐๐ฒ๐ ๐๐ป๐๐ถ๐ด๐ต๐:
Itโs important to note that visible leaks on the underside of a concrete slab donโt always indicate the exact point of water entry. Water can migrate through construction joints, and movement joints before becoming visible below.
๐๏ธย ๐ฆ๐๐ฟ๐๐ฐ๐๐๐ฟ๐ฎ๐น ๐ข๐๐ฒ๐ฟ๐๐ถ๐ฒ๐:
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.
Weโre now working closely with the client to develop a robust waterproofing solution tailored to the unique challenges of this buried deck system.
๐นSemi-Basement Extension, Salisbury: Following our pre-construction waterproofing survey, our technicians are now on site installing aย ๐ง๐๐ฝ๐ฒ ๐ ๐ฐ๐ฎ๐๐ถ๐๐ ๐ฑ๐ฟ๐ฎ๐ถ๐ป ๐บ๐ฒ๐บ๐ฏ๐ฟ๐ฎ๐ป๐ฒ ๐๐๐๐๐ฒ๐บย to protect the newly built semi-basement extension at thisย ๐๐ฟ๐ฎ๐ฑ๐ฒ ๐๐ ๐น๐ถ๐๐๐ฒ๐ฑย property in Salisbury.
Although not a full basement, the structure still requires effective protection against water ingress to ensure it remains dry and habitableโfully compliant withย ๐๐ฆ ๐ด๐ญ๐ฌ๐ฎ:๐ฎ๐ฌ๐ฎ๐ฎย standards for below-ground waterproofing.
๐งย ๐๐ฟ๐ฎ๐ถ๐ป๐ฎ๐ด๐ฒ ๐ฆ๐๐ฟ๐ฎ๐๐ฒ๐ด๐ โ Gravity-Fed System:
As part of our design, we offered the option of aย sump and pump systemย to manage any potential water ingress. However, the client opted for aย gravity-fed drainage solution, which is a passive system that relies on natural fall to direct water away from the structure.
This approach involves:
โ
๐๐ฟ๐ฎ๐ถ๐ป๐ฎ๐ด๐ฒ ๐ฐ๐ต๐ฎ๐ป๐ป๐ฒ๐น๐ย integrated at the base of the cavity membrane system.
โ
๐ฃ๐ถ๐ฝ๐ฒ๐๐ผ๐ฟ๐ธ ๐ฐ๐ฎ๐๐ ๐ถ๐ป๐๐ผ ๐๐ต๐ฒ ๐๐น๐ฎ๐ฏย designed with sufficient fall to ensure continuous flow.
โ
๐ ๐ป๐ผ๐ป-๐ฟ๐ฒ๐๐๐ฟ๐ป ๐๐ฎ๐น๐๐ฒย 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.
Weโre proud to support projects that combine modern construction with heritage sensitivityโdelivering long-term protection and peace of mind.
