Product Overview

SIKA BENTOSHIELD MAX LM 1.1 x 5m

A self healing waterproofing membrane that is resistant to contaminated soils, forming an automatic mechanical bond to freshly poured concrete. Unit Size: 1.1m x 5m rolls

Uses:
◇ Damp proofing, water proofing, tanking membrane for horizontal and vertical applications where buildings are expected to be subject to hydrostatic water pressure
◇ Below ground reinforced concrete structures
◇ Effective against diaphragm wall constructions
◇ Direct application onto ground retaining concrete piling when placed within the piling – concrete interface
◇ Direct application within steel sheet piling – concrete interface
◇ Can be placed within the formwork
◇ Below structural reinforced concrete slabs

Advantages:
◇ Qualified waterproofing tanking membrane in accordance with BS8102:2022
◇ Water tightness of the laps tested to BS EN 1928
◇ Designed to offer protection in areas subject to changing geological conditions such as flood plains, areas of soil settlement and brown field constructions
◇ Application ensures performance stability in high water table environments and constructions which are subject to future alterations in water levels.
◇ An effective barrier against ground water in saline environments
◇ Easy to install, no primers required
◇ No protection boards required
◇ Can be applied in temperatures below 0°c
◇ Will self heal when subjected to a head of water (damaged area size less than 2mm. Self healing varies subject to moisture, confinement and compression levels.)
◇ Can be applied during conditions of high humidity
◇ Major constructions benefit from speed of application
◇ 0.3mm PE backing gives effective Radon barrier in accordance with BRE211.

SIKA BENTOSHIELD MAX LM 1.1 x 5m – Incredible Self-Healing Tanking Membrane

The SIKA BENTOSHIELD MAX LM 1.1 x 5m is a premium quality, high-performance structural solution engineered to deliver exceptional protective and tanking properties for the modern construction and civil engineering industry. As shown in the detailed multi-layered sub-slab layout of the product image, each roll consists of an advanced waterproofing barrier designed to form an automatic mechanical bond to freshly poured concrete. Choosing the SIKA BENTOSHIELD MAX LM 1.1 x 5m ensures a superior product that allows builders to construct a secure, unyielding barrier over horizontal and vertical assemblies with minimal installation complexity, leading to far more rigid, airtight, and dependable sub-floor isolation systems.

By integrating the heavy-duty SIKA BENTOSHIELD MAX LM 1.1 x 5m into your primary foundation and retaining wall layouts, you guarantee a much higher defense against groundwater ingress and maximum structural safety. This makes the SIKA BENTOSHIELD MAX LM 1.1 x 5m the absolute go-to choice for site managers and contractors who refuse to compromise on build quality, density, and overall foundational stability.

Key Benefits and Performance

• Automatic Mechanical Bonding: Engineered to form an instant, continuous mechanical bond directly to freshly poured concrete, preventing any water tracking between the structure and the sheet.

• Intelligent Self-Healing Core: Formulated to self-heal autonomously when subjected to a head of water for damaged area sizes less than 2mm, providing resilient long-term safety.

• Contaminated Soil Resistance: Specifically developed to maintain full performance stability in contaminated soils and harsh saline environments.

• Geological Shift Protection: Designed to offer top-tier protection in areas subject to changing geological conditions, including flood plains, brownfield sites, and soil settlement zones.

• BS 8102:2022 Qualified Tanking: Fully qualified as a high-specification tanking membrane in accordance with modern BS 8102:2022 building standards, while lap watertightness is rigorously tested to BS EN 1928.

• Integrated Radon Gas Barrier: Built with a specialized 0.3mm PE backing that delivers an exceptionally effective Radon barrier in accordance with BRE211 guidelines.

• All-Weather Worksite Efficiency: Highly optimized for rapid on-site installation with no primers or independent protection boards required; can be applied in high humidity and temperatures below 0°C.
