Application

Ash GP blocks suit all general-purpose walling applications. It is recommended that walls of 215mm thickness are constructed using 100mm blocks laid flat.


Can be used to construct internal walls in commercial, industrial and leisure buildings. The blocks can be used for the following:


  • The inner and outer leaves of external cavity walls
  • Internal walls including fire break walls
  • Separating walls including those conforming to Robust Detail specifications
  • Below ground (7.3N/mm2 strength blocks should e used for walls that are exposed to the external ground)
  • Infill units to beam and block flooring using 7.3N/mm2 or 7.3N/mm2 blocks*


*3.6N/mm2 blocks have been transverse tested to ensure suitability.


The design of walls using Ash GP blocks should be in accordance with relevant design standards, including BS 8103: Part 2 and BS EN 1996-1-1 and the requirements of the Building Regulations.

Description

Ash GP medium density concrete blocks are robust and durable, making them the perfect choice for walls built above and below ground. Manufactured to BS EN 771-3, their textured faces provide an excellent surface for mortars, renders and plasters. They also provide a strong base for holding fixings.


Ash GP blocks contain a proportion of recycled materials, and their sustainability performance has been verified through an Environmental Performance Declaration (EPD).


Features and benefits:

  • Also available in 140 mm thickness (specified separately).
  • Also available in mean unit strengths of 7.3 or 10.4 N/mm², in both in 100 or 140 mm thicknesses (specified separately).
  • Robust and durable.
  • Good surface key for the direct application of plasters and renders.
  • For use internally and externally, above and below ground.
  • High levels of air tightness, sound insulation and fire resistance.
  • Provides a strong background for holding fixings.
  • Over one-third of the materials come from sustainable sources.
  • Credits available under BREEAM and Code for Sustainable Homes.
  • CE marked to BS EN 771-3.
  • Can be used to satisfy the requirements of Part L of the Building Regulations.
  • Good technical performance, high recycled content


Sound properties:

Ash GP blockwork provides excellent levels of sound insulation between buildings and adjoining rooms. It can be used in cavity party wall constructions in dwellings, satisfying the specifications for lightweight blockwork in accordance with Building Regulations’ Approved Document E. It can also be used to construct party walls meeting Robust Detail specifications (e.g., Robust Details E-WM-2, 4, 8, 11, 14, 17, 20, 21, 22, 27, 28 and 33).


Mortar:

Generally, the mortar type for work above ground level should be designation (iii) / Compressive Class M4. Designation (ii) / Compressive Class M6 is needed for work below ground in conditions where there is a risk of saturation with freezing.


Movement joints:

Vertical movement joints should be considered in accordance with masonry design codes and the recommendations of Published Document PD 6697, at 6.0-8.0 metre spacings. In areas of raised stress, such as above and below openings in external walls, the blockwork may need to be reinforced to restrain movement.
