self build waterproof basement formwork membrane concrete insulation
 

How I save my customers money.

There are so many ways money can be wasted when you don't have much experience doing something you have never done before.

In general, the construction industry builds basements that leak. That is why there is a plethora of products to spend a huge amount of money on that claim to improve workmanship or solve the problems created by poor workmanship.

The absolute truth is that you don't need any of them if you don't have poor workmanship. But your architect and your engineer will be keen to protect themselves by telling you to use a whole host of expensive stuff, whether it actually does any good or not.


Projects where I helped generally went well. Customers became friends.

They spent money with me on a mixture of the following.


Training Supervision Products
Months before building starts I am paid to answer all your emails. I will discuss anything. I will explain everything in good time. £99.
My first day on site is usually showing men how to tie slab steel. I take the opportunity to discuss the slab/wall joint and wall formwork and what will be expected. £300. Delivery of rods for the slab levelling system. £2.50 per m.
My second day on site will be waterproofing the slab concrete and supervising the pouring of the slab concrete. I bring vibrating pokers and make test cubes if a certificate is required.
Day on site £300.
Poker hire £80 for two powerful pokers, one to use and a spare.
Testing a set of cubes to prove your concrete is waterproof costs £735 at the lab.
Powerful plasticiser to waterproof the slab concrete. £23 per m³ treated.

Delivery of rods and nuts for the wall formwork. Rods £2.50 per m and nuts £1.50 each.
My third day is often showing the men how to tie wall steel.
When the men are getting on with steel tying, I go through how to build the formwork with the foreman.
Day on site £300.
My fourth day on site will be waterproofing the first wall concrete and supervising the pouring of the wall to half height or a bit higher as agreed. I bring vibrating pokers again.
Day on site £300.
Poker hire £80 for two powerful pokers, one to use and a spare.
Powerful plasticiser to waterproof the slab concrete. £23 per m³ treated.
My fifth and last day on site will be waterproofing the second wall concrete and supervising the pouring of the wall to the top. I bring vibrating pokers again.
Day on site £300.
Poker hire £80 for two powerful pokers, one to use and a spare.
Powerful plasticiser to waterproof the slab concrete. £23 per m³ treated.
Total for training £699 Total for supervision and poker hire £1140
Please note, the test cost goes to the lab.
Total for waterproofing plasticiser, rods and nuts depends on the size of your project.
I also sell a better external drainage membrane for less money than the branded alternatives.


If you spend your money with me and you and your team do as I explain and direct I will guarantee that your concrete structure is waterproof and I will personally fix any visible ingress of water free of charge.

This is the best guarantee of its type available in the UK.

The same slab finished - and sprayed with water to prevent surface cracking because this was a very hot day.




Please note. Any project too far away for me to travel and back in a day will be subject to accommodation charges at cost - if I agree to do it.


I am not VAT registered any more. The VAT on supervision and training was not recoverable anyway, even on a new build dwelling. In particular, not adding VAT saves people extending an existing home money.

I don't give credit. All payments just in time in advance against emailed invoice.
