Larsen Streetscape PS Eco Priming Slurry 25kg | BS 7533 Bonding Mortar

Larsen Streetscape PS Eco Priming Slurry from Larsen Building Products is a high-performance reduced-carbon bonding mortar specifically developed for use within BS 7533 compliant bound paving systems. Designed to maximise adhesion between paving units and bedding mortars, PS Eco provides a critical bonding layer that enhances pavement strength, durability, and long-term performance.

Formulated to exceed the minimum ≥2MPa adhesion bond strength requirement specified for Bound System B within BS 7533 Part 101, Streetscape PS Eco is designed for use in conjunction with Larsen Streetscape FBC Eco Bedding Mortar and FBC Eco Permeable Bedding Mortar. The advanced formulation ensures excellent bond performance when installing natural stone paving, concrete paving, clay pavers, setts, and other modular paving units.

As part of Larsen’s Eco range, PS Eco incorporates reduced-carbon technology to support sustainable construction projects while maintaining the high-performance standards required for commercial, public realm, and infrastructure developments.

The carbon savings achieved through the use of PS Eco are equivalent to the carbon absorbed by growing one tree for ten years or avoiding approximately 107 miles of vehicle travel per tonne of product used.

Ideal for highways, streetscapes, public realm schemes, pedestrian areas, commercial paving projects, and landscape installations, Streetscape PS Eco provides reliable adhesion and sustainable performance in demanding paving environments.
