Why use HESplus

The short answer is that using HESplus together with hydrated lime has multiple benefits compared to other binders on the market such as natural hydraulic lime (NHL) , hydraulic lime (HL) and cements.

Summary of benefits CO2 absorbing (proven results), lower emissions, cost savings, more insulative and lightweight, tried and tested, unlimited shelf life, US patented.

First, Hydrated lime

One of the keys to what makes HESplus so good, is that we are able to once again use hydrated lime for construction. Hydrated lime is an abundant resource which is used for water purification, Metal production, soil stabilization, agriculture and more. Not to forget that much of our ancient civilization was built using hydrated lime. Hydrated lime is also used for plaster work and various finishes and can be soaked in water for many years to improve the quality, Hydrated lime has excellent moisture retention quality which makes it a desirable additive to conventional concretes and cement based plasters...

Lets go into the detailed benefits of using HESplus

  1. Proven to allow continuous carbonation of hydrated Lime (Calcium hydroxide) while speeding up the initial setting time. This means that CO2 Is absorbed by the hydrated Lime and the lime cycle continues eventually turning back into Limestone (calcium carbonate)

  2. Reduced emissions and Cost savings benefit (for your pocket and the environment) because of the ability to use locally sourced high calcium hydrated lime, this means that only a small quantity of HESplus (1 pallet for a house) needs to be transported which will bring down the overall cost.

  3. Using HESplus and hydrated lime allows us to reduce the total amount of binder compared to other binders which produces a more porous, thermally insulating and homogenous mix.

  4. HESplus and Hydrated lime mixed with Hemp hurds produces HESmix. HESmix has been tried and tested according to EN standards for fire Resistance, thermal conductivity, water absorbtivity, strength tests and more, It also had been used in over 50’000m2 of buildings and renovations.

  5. Unlimited shelf life means that you can order one pallet of HESplus for your building project now and store it in your garage until you are ready to build. Hydrated lime can be sourced locally as and when needed and unlike other Hydraulic binders, you will not have to risk throwing it away because it has started setting.

  6. HESmix is the original HempLime and is a US Patented formula. Be careful of other binder products that claim to use hydrated lime and natural minerals that offer the same or similar benefits to the above.

I hope this provided some further insight into the benefits of using HESplus for your next project.

In the UK hydrated lime is commonly added to cement for increased plasticity/cohesiveness, but doesn't have any setting properties. How does this work for your HESplus, or is it a different sort of hydrated lime?

Replying to

HESplus is an additive that we add to hydrated lime to increase the curing time, instead of using hydraulic lime. While still allowing the lime to continue it's carbonation process therefore allowing the house to still 'breathe'.
