This is like a scene from the battle of the Somme. It actually shows the internal drainage along the North wall of the mill. The foundations are completely saturated at this point in time. The ground water level in this space was less than two feet above the river outside. The drainage inside the mill has transformed this situation.
The forge is a chance to try out many of the materials and methods that we will use on the mill. This includes the insulation regime.
Here you see a good thick layer of wool lining the walls. What you cannot see is the space age, breathable multi-foil insulation layer just under the weatherboarding. We're already surprised at the difference it all makes to both noise and thermal performance.
When we found this enamel sign in the mill, it was so dirty that we thought it was just one of a number of sheets of rusty metal.
The sign is advertising animal feed from a company called R&W Paul Ltd, an Ipswich based company founded in 1842. The brewery diversified into the manufacture of animal feedstuffs after 1877.
The company was eventually sold to the Irish-based agriculture and sugar conglomerate, Greencore.
Oakley framers work as a well oiled team. They don’t stop but keep up a steady relentless pace moving heavy oak posts and beams. The four of them loaded and unloaded 9 tons of garage materials and drove down from Corby all before 11am. By evening the oak frame was up.
“Weeping walls" can be impregnated gently with slower curing mixtures of resin. The water is effectively pushed out of the wall as the expanding resin “freezes” forming a waterproof structure inside brickwork and replacing water and lost grouting.
As this barrier cures, the pressurised resin bleeds backwards to the near side of the wall where it leaks out of every nook and cranny as it forces the water from the wall. The curing resin is shown dribbling down the wall. These white rubbery streams are easily removed when the resin solidifies.
After six months the wall is now dry and happy. The whole building is far more airy and theres a feeling of warmth in the place that’s never been there before.
The team from Oxford Hydrotechnics injected a hydrophobic resin that is thinner than water into the structure of the wall. This is a common cure for serious leaks in tunnelling applications encountering subterranean water.
The resin can be brewed to cure at different rates. When the resin meets water it reacts by rapidly expanding up to twenty-fold in volume. Big leaks can be quenched instantly by quick acting resin that forms a waterproof flexible foam that fills large voids and blocks large holes.
