TOPCRETE Standard

Dense Concrete Block

Overview

Topcrete Standard is a dense aggregate concrete block.

Topcrete Standard blocks are manufactured with dense aggregate, so they are more robust and durable in building applications where strength is required.

This makes Topcrete blocks suitable for a much wider range of building specifications due to the range of strengths and formats of the blocks available.

Topcrete blocks are suitable for use in walls above and below ground as well as beam & block floors due to the proven high level of technical performance.

Where can TOPCRETE Standard be used?

Cavity walls above and below DPC

Topcrete blocks can be effective in walls above and below the DPC (damp proof course).

Separating walls

Buildings require resistance to sound transmission to meet building regulations, Topcrete standard blocks are ideal for use in separating walls due to their acoustic performance.

Beam and block floors

Topcrete standard aggregate blocks can be used in beam and block floors. Quick installation being a benefit for use in suspended floors in conjunction with precast concrete beams.

Cavity walls

Topcrete blocks are high performance blocks available in a range of strengths suitable for constructing internal and external walls above and below ground.

Solid internal walls and external walls

Topcrete Standard blocks can be used for internal and external walls. These concrete blocks provide good levels of airborne sound insulation as well as having a suitable background for fixings and finishes.

When used for external walls the blockwork should be rendered or clad.

Loadbearing walls

Topcrete standard blocks come in a range of strengths for different building applications making them ideal for loadbearing walls

Why use TOPCRETE Standard?

Topcrete Range

Topcrete blocks are available in a range of strengths and formats to suit your building needs. They are produced in solid, hollow as well as multicore and midi formats to meet different structural applications in walls above and below ground as well as beam and block floors.

When estimating Midi Blocks the following number of blocks are required per m2 of laid wall, based on using 10mm mortar joints

  • 140mm width = 15 blocks
