Description

The taller 625 × 240 mm face from Hi-Tech, for sites that want fewer courses per floor. Hi-Tech also makes the joint mortar and the plaster, so the whole wall can come from one maker.

Laying AAC with thin-bed mortar
  1. Lay the first course on a level bed of normal sand-cement mortar to take up slab unevenness.
  2. From the second course, mix joint mortar with 25–30% clean water to a smooth paste.
  3. Spread it 2–3 mm thick with a notched trowel as wide as the block, on bed and vertical joints.
  4. Tap each block to line and level with a rubber mallet. Stagger vertical joints by at least 100 mm.
  5. No curing needed. Plaster or putty can follow once the mortar has hardened.
Delivery and unloading

Blocks are sold by the cubic metre and travel strapped on pallets. One truck carries up to 33 m³; bigger orders are split across trucks. Joint mortar and cement bags ride on the same truck, or come on their own if you order chemical only. Tell us the floor, road access and whether a crane or hoist is available when you check out, and we'll plan the drop.
