As well as large industrial and commercial sites, PUDLO also undertakes residential and private projects. Creskeld Manor is a Grade II listed country home on the outskirts of Leeds. The proprietor wished to install a swimming pool, hot tub and plunge pool on the sloping site. PUDLO was engaged by Topline Developments to address the ground water risk and provide an appropriate waterproofing solution.Creskeld Manor

Problem

Due to the client’s requirements and expectations, and the nature of the sloping site heightening risk of ground water permeating the swimming pool, PUDLO employed three lines of defence. When installing a water-retaining structure, both the ingress and egress of water need to be considered. Over time, the filling and emptying of the pool could result in failure of its structure. Installing three different systems dramatically reduces the risk of this occurring, as well as ensuring the longevity of the structure’s waterproofing.

Solution

In order to thoroughly protect the project, Types A, B and C waterproofing were installed as per BS 8102:2009.

Type A: The membrane

427m2 of PUDLO BW membrane was pre-applied to form external waterproofing around the pool itself and the surrounding floor slabs. This bentonite system is a self-sealing product that’s quick to install and requires no tape on overlaps or joints. The geotextile sodium bentonite membrane is self-healing, to ensure a long-lasting waterproof seal.

Type B: The concrete

60m3 of PUDLO modified waterproof concrete was used to form the water-retaining structure. PUDLO’s coveted waterproof concrete ensures that no water could pass through the swimming pool walls – including ground water entering the pool, or pool water expelling into the surrounding ground. The waterproof admixture is mixed into the concrete at the batching plant, ensuring thorough dissemination throughout the pour.

Type C: The drainage

PUDLO Cavity Drain System consists of a studded membrane. The membrane is installed internally to walls and floors to manage any moisture seepage through the structure. This acts as a backup to the primary barrier and formed the final line of defence against ground water.

To ensure the accurate installation of these products, every concrete pour was attended by PUDLO’s QA (quality assurance) site support team, which is second to none. It’s their job to check the process and practises being used in any prep work, as well as ensuring the concrete tickets and mix design are consistent with their guidelines. Our uniquely experienced site support team is integral in the approval of our product and performance warranties.

Both PUDLO and Topline Developments were completely satisfied with the conclusion of this project, which led to PUDLO being referred for further projects across the Lake District area.
