Looks good... can't find a price guide on their site (?)
The claims are clear, the idea seems perfectly reasonable, they seem keen to do a good job and proud of their work, and you can't really argue with a lifetime guarantee.

I can't pick any fault in their efficacy claims.
I am curious though about the houses with a second row of the special bricks at first floor level. Were the houses built in a swamp?

The airbrick units are a bit obvious located so high above ground level in the external wall so it's not a neat unobtrusive solution but if it works... usually damp in external walls is a sign of something underlying so it isn't necessarily treating the problem.

Something similar has been around for some time.

...the ceramic pipes don't work though Ian.
What isnt clear is how the +ve and _ve pressures are set up within the baffle of the Schrijver system as normally the differential is created by air pressure across a building, eg the roof ridge or cross ventialtion from the windy side to the leeward side, but in the airbricks the air won't flow from a +ve area to a _ve area, so the cross flow can't work in practise.

If you do anything in the UK affecting your damp proofing it needs to pass UK building regs. So perhaps really down to if it meets uk regs or not.

Arch's Mum has had the same system fitted in her house. Arch might be able to solicit some feedback.
I am undecided though, it really depends on the reasons and causes of any dampness and whether it has been dealt with first.
I have two areas of my house that get damp. The little bits around the valley gutters that are due to minor gutter overflowing or wind driving water up the gutter sides, and the dampness that coincides with a leaky rainwater pipe.
Fixing both will solve the problem.
The other area of damp used to come from having a basement that flooded in the rain. The water came up through the floor.
A DPC and land drains under the new floor sorted that.
I am slowly going around the house replacing the drilled bricks from the injection system that my mortgage lender insisted on having despite there being no dampness above the slate DPC in the brickwork.
