Tytan foundation horizontal insulation foil 0.365 x 50 m 0.3 mm

Tytan foundation horizontal insulation foil 0.365 x 50 m 0.3 mm is a polyethylene damp-proof course designed for installation beneath foundations and between masonry layers to prevent rising damp and capillary moisture transfer. The roll measures 0.365 m in width and 50 m in length with a 0.3 mm thickness, offering a continuous, flexible barrier suitable for new construction and repair works. The material is intended for embedding at footing level, under concrete strips, and between courses of brick or blockwork where a reliable horizontal moisture barrier is required.

Advantages

The foil provides a continuous polyethylene barrier that resists water migration and capillary action while remaining flexible for ease of installation around irregular surfaces. Its 0.3 mm thickness balances durability and pliability, allowing it to withstand normal construction handling and embedding in mortar without tearing. The product is compatible with common masonry and concrete materials and can be used in both new-build and refurbishment projects where a horizontal damp-proof course is required.

Suitable for

• Creating a damp-proof course under strip foundations and footings
• Placement between brick or block courses to prevent rising moisture
• Repairing or upgrading existing horizontal damp-proof layers
• Use beneath concrete ground beams and slab edges to isolate moisture

Key specifications

• Material: polyethylene film
• Width: 0.365 m
• Length: 50 m per roll
• Thickness: 0.3 mm
• Form: continuous roll for horizontal installation

How to use

Unroll the foil and position it on a clean, level surface at the required elevation beneath foundation concrete or between masonry courses. Overlap adjacent sheets according to local standards or building regulations to ensure a continuous barrier; joints can be sealed with compatible adhesive tape or mortar bedding where specified. Protect the foil from sharp objects and excessive movement during backfilling and concreting. When embedding in mortar, ensure full contact with the bedding layer to avoid folds or air pockets that could compromise the seal.

Usage recommendations

Store rolls in a dry, shaded area away from direct sunlight and temperatures well below freezing. During installation, avoid contact with solvents or hot bituminous products that can damage polyethylene. For best performance, follow applicable national building codes regarding overlap dimensions, joint treatment, and integration with other damp-proofing measures.
