Description

Marshalls Keykerb is a small unit system designed to be fully compatible with the majority of concrete paving types, in a range of colours to match the paving. The system comprises three basic types for straightwork; Keykerb Large, Keykerb Medium and Keykerb Small.

Keykerb Large (KL)

Manufactured in Bullnosed (BN) and Half battered (HB) profiles, for laying with a kerb upstand of 100–125 mm. The Half battered profile is also designed for laying ‘flat’.

Keykerb Medium (KM)

Has a deeper profile than Keykerb Small (KS) for improved stability and incorporates a 50 mm deep, 45° splay to the kerb face.

Keykerb Small (KS)

Intended for laying with a 25–50 mm kerb upstand and would normally be used in courtyard, car park, landscape or domestic applications. Manufactured in Splay (SP) and Bullnosed (BN) profiles.

PhysicalPropertiesWeatheringResistance

≤1.0 kg/m² as a mean with no individual value > 1.5 kg/m² (freeze thaw durability). It should be appreciated that with all products weathering and site conditions can cause shade variation to appear across the surface of individual units. This does not in any way affect the performance of the units and any such variation will diminish over a period of time as the product matures
