OVERVIEW

The Whittle Estate is a modern industrial and warehouse development located in Whetstone, Leicester. Overseen by Triton Construction, the scheme provides high-quality commercial units designed to meet contemporary logistics and industrial demands, with completion targeted for 2026.

Given the nature of the development and the requirement for durable, long term performance, a robust waterproofing strategy was critical, particularly within below-ground structures and exposed concrete elements.

WATERPROOFING STRATEGY

To achieve a high-performance waterproofing solution, a combined system was adopted
incorporating:

• Xypex crystalline waterproofing technology
• Delta Membrane Systems Ltd Delta Amphibia external membrane system

This dual approach ensured both integral waterproofing within the concrete matrix and
external barrier protection, aligning with best practice for structural waterproofing design.

XYPEX TECHNOLOGY

Xypex crystalline waterproofing was used to enhance the durability and impermeability of
the concrete. The system works by forming crystals within the concrete structure, reducing
permeability and enabling self-healing of microcracks over time.

This approach provides long-term protection and eliminates reliance on surface-applied systems alone, contributing to extended service life and reduced maintenance requirements.

INSTALLATION & REMEDIAL WORKS

During construction, some areas of honeycombing were identified within the
concrete. These were addressed through a structured remedial process:

• Defective areas were broken out by the groundworks contractor
• Reinstatement was completed using Manorteq Readyproof R4 structural repair mortar
• Repairs ensured structural integrity and continuity of the waterproofing system

This proactive approach ensured that all compromised concrete was rectified prior to final
waterproofing performance being relied upon.

INTEGRATION WITH DELTA AMPHIBIA SYSTEM

The use of the Delta Amphibia external membrane provided an additional layer of
protection, particularly suited to:

• Below-ground applications
• Areas subject to potential water ingress
• Structures requiring combined Type A and Type B waterproofing protection

The compatibility between Xypex and the external membrane system allowed for a belt-and-braces waterproofing strategy, reducing risk and enhancing overall system resilience. The Delta Amphibia membrane can also function as a radon barrier.

TECHNICAL SUPPORT FROM SMR PROJECTS

The Xypex waterproofing system was supplied by SMR Projects Ltd, who played a key role beyond material supply, providing hands-on technical assistance.

SMR Projects provided:

• On-site support from Site Service Technicians
• Installation guidance and quality assurance advice
• Practical recommendations for detailing and sequencing

Their involvement ensured that the system was installed in accordance with best practice and manufacturer requirements.

This approach reflects SMR Projects’ wider methodology, where early-stage technical
collaboration and site engagement help optimise waterproofing performance and reduce construction risk.
