Tradical Hemcrete

Lime Technology has launched Tradical ®Hemcrete®, a new product innovation of cast in situ hemp-lime walling. It comprises a unique blend of specially prepared hemp shiv (Tradical® HF) and a special lime based binder (Tradical® HB); which together form a bio-composite building material. The hemp, which forms the key element in these products, is largely grown and havested in the UK. Tradical ®Hemcrete® provides one of the best value materials for low impact, sustainable and commercially viable construction.

Ready-mixed Hydraulic Mortars and Sprayable Plasters

There are three standard mortars which cover a range of likely applications both for conservation and new build. These are as follows: -

Limetec eminently hydraulic mortar

For use where a higher level of durability is required; i.e. masonry exposed to severe weather.

Limetec moderately hydraulic mortar

For most normal applications i.e. cavity brickwork, blockwork and stonework.

Limetec feebly hydraulic mortar

For use with softer bricks and stone, solid wall construction and conservation masonry.

Lime Putty Mortars and Plasters

Back to Earth lime mortars and plasters use the finest Buxton Lime, local sands and rainwater harvested from the roofs of our buildings to produce high quality products ideal for building conservation.

Coarse mortar

Manufactured with a high quality, extremely versatile coarse sharp sand to give a very low shrinkage multi purpose mortar - used for pointing, bricklaying, stonework, rendering and plastering. This product is sold in 1000kg bags or to special order in 25kg tubs.

Finishing plaster

Manufactured with a fine silver sand (a waste product of the China Clay industry) and ultra fine quicklime to produce a finishing plaster with low shrinkage and good finishing properties. This product is sold in 25kg tubs.

Natural Hydraulic Limes

During the last 25 years, Lime has enjoyed a steady revival for repairs to historic buildings. The soft, porous and flexible nature of lime mortars and plasters is now universally recognized as being vital to maintain the traditional breathing performance of old buildings. In addition, an increasing number of architects, engineers, surveyors and builders are now beginning to realise that lime has many benefits to offer in new construction: provides one of the best value materials for low impact, sustainable and commercially viable construction.

Naterra

Developed through a project sponsored by the Waste Resources Action Program (WRAP), these blocks contain a mixture of clay with just over 50% recycled plasterboard.

Earth Blocks

Sumatec

These compressed earth blocks, made from brick-making waste, have been developed to combine extremely high strength, high thermal mass and good acoustic properties.

Hemp Blocks

We offer two types of blocks for low carbon construction. The load-bearing block is a carbon-neutral block with excellent thermal capacity and high compressive strength. The insulating block is a non-load-bearing, carbon-sequestering block with excellent insulation properties.

NBT Thermoplan System

This is a thin-bed insulated structural solid wall system. The blocks are made from fired aerated clay, planed to extremely high tolerances, laid in a very thin joint mortar for incredibly fast construction.

Cob Blocks

These blocks are locally made for conservation and restoration works. They are extruded and air-dried in the sun to give very low embodied energy.

Clay Bricks

These unfired bricks are used for coursing around lintels, etc. in new cob block work or for small repairs to cob buildings.

Hemcoat Insulating Plaster

This renovating/insulating plaster, made from a finer grade of hemp shiv than used in Tradical Hemcrete, can be used to build up substantial thicknesses of plaster to upgrade existing solid walls. It is ideal for use in barn conversions or for renovation of cob/stone/brick/buildings.

Breathe Hemp Insulation

A more efficient thermal and acoustic insulation than mineral wool, manufactured in the UK from UK-grown hemp. Breathe is excellent for the installer as it is not an irritant; and for every 10kg you use, you lock up just over 18kg of CO2

NBT Pava and Diffutherm Systems

Both ranges are based on a board made from waste wood fibre, which gives high insulation and remains breathable.

The board itself is impregnated with various materials depending on its application; and can be used even for steel and timber framing. These sytems offer extremely fast construction with very good results.
