H+H UK LTD manufacture a wide range of Concrete Blocks and lightweight Concrete Blocks to suite all types on Block Construction.

Useful Resources:

H+H is the UK’s largest manufacturer of aircrete products. We manufacture the market leading range of Celcon Blocks, including Foundation Blocks, Plus Blocks and the H+H range of aircrete products.

H+H aircrete products offer a complete building material that meets the requirements of the Building Regulations, with the flexibility to offer solutions to hospitals, schools, offices, industrial warehouses and housing (social and private).

Used in partition, separating and external walls (solid or cavity), firewalls and as an infill to framed construction, our products provide durability and fire resistance as well as superb thermal and sound insulation.

Main Product Ranges:

Celcon Blocks

Celcon Blocks in Solar, Standard, High Strength and Super Strength Grades are the most commonly used aircrete block in the H+H range. All Celcon Blocks are BBA certified, are fire resistant (100mm walls, up to 4 hours, 2 hours if loadbearing) and have been classified 0 surface spread of flame and non-combustible to Class A1 (the highest class).

Celcon Block Solar Grade

Celcon Blocks Solar Grade is principally used where enhanced thermal performance is required. With superior thermal conductivity Solar Grade Celcon Blocks are suitably loadbearing for two storey buildings and can be used below DPC.

Celcon Block Standard Grade

Celcon Blocks Standard Grade is BBA certified and has a compressive strength of 3.6N/mm2. Due to its all round performance, it is possible for a 100mm Standard grade Celcon Block to be used throughout a build, eliminating on-site confusion.

Celcon Block High Strength & Super Strength Grade

H+H’s Celcon Blocks High Strength Grade (7.3N/mm2) and Super Strength Grade (8.7N/mm2) are used principally where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multi-storey buildings.

Celcon Plus Blocks

Celcon Plus Blocks are an alternative to the 440 x 215mm face format block and are suitable for the same applications.  They are longer at 630mm long and come in a variety of thicknesses.

Celcon Foundation Blocks

Available in Standard Grade (3.6N/mm²) and High Strength Grade (7.3N/mm²), Foundation Blocks can be used to support 3 storey constructions.  They are suitable for the support of solid or cavity walls, framed construction or suspended floors, including beam and block.

Beam & Block Floorblock

Beam and Block floors are constructed using Celcon Blocks. They are lightweight, so easier, quicker and safer to lay and allow for an economy of scale and reduction in laying times.

Multi Plates

H+H Multi Plates are a new generation of aircrete products that build on the efficiency of thin layer construction. At over 2 times the size of a traditional (440 x 215mm) block, Multi Plates and the Thin-Joint system will deliver significant savings in site productivity.

Jumbo Bloks

Jumbo Bloks are produced with the latest technology, offering a high degree of dimensional accuracy with sharp arises, which make them ideal for use with Celfix mortar.

Celcon Block Coursing Units

Coursing Units are produced from the same material as all H+H aircrete and are suitable for the same applications as conventional size Celcon Blocks, allowing consistency within the building fabric.

Celfix Mortar

Celfix Mortar is cement based and supplied as a dry, pre-mixed powder in 25kg bags. It has been designed to replace the traditional sand:cement mortar and is used with building with our Thin-Joint System. Celfix Mortar starts to set within 10 minutes of application and approaches full design strength in just 1 to 2 hours.

Transport Safety: A Live Issue for H+H

April 2020

Working at height is always a potential danger point, and the team at our Pollington plant have taken some radical action to reduce risk.

HSE figures suggest that the most dangerous point of any product haulage process is the loading and unloading of vehicles. It’s a widely recognised problem, with statistics suggesting that some 250 people suffer significant injuries each year as a result.

The team at Pollington decided that it was time to entirely redesign our loading procedures to eliminate this risk as far as possible. We see it is our responsibility to ensure that all visitors to our site are safe.

It may sound like a minor change, but in fact it is anything but. Challenging long-established routines and asking people to change familiar behaviours takes tact, time and commitment.

Visitors to the yard will immediately notice the difference as there is a strict one-way system and the routes for delivery vehicles are now completely separate to those used by cars.

Traffic flow is important, but the major risk occurs when people climb onto lorries during loading. Understanding just why this happened needed a thorough examination of the packing and stacking procedures.

From that point a new method of loading the lorries was designed, in close co-operation with our haulage company and with the HSE to make sure that Highways England were happy with the safety of the new loading systems.

It’s one thing to introduce a new procedure and quite another to make sure it sticks. New signage in the yard, including detailed diagrams of stacking procedures, is very evident and a drivers’ handbook has been placed in every lorry that visits the H+H yard.

Three months into the reorganisation and the yard is looking more orderly than ever. Waiting times are dramatically reduced as the new system is much more efficient but, most importantly, we are demonstrating our commitment to ensuring the safety of both our staff and our visitors.

H+H UK COVID-19

April 2020

Due to the current Coronavirus situation and the recent measures taken in the UK overall, H+H Ltd has temporarily adjusted its manufacturing operations in the UK to ensure its continued commitment to our people and their safety.

We have product in stock and will continue to staff our distribution yards to ensure that H+H Aircrete can be supplied in support of our customers and we will ensure all appropriate safeguards are in place to protect staff working in these facilities.
