Newton Waterproofing saves double basement failure in Notting Hill
N
ewton Waterproofing and their Specialist Contractor Stonehouse have delivered an exceptional waterproofing design and installation for a large, two-level basement in Notting Hill, resulting in a stunning watertight and guaranteed new living space beneath the home. The UK’s leading suppliers of guaranteed waterproofing systems were approached by the desperate client who had had a second basement level excavated beneath their existing basement as well as the front and rear gardens. Unfortunately, bad waterproofing design and workmanship meant the basement had flooded immediately upon completion – the builder ceased trading and, following a legal case, the architect and structural engineer were found culpable. Newton Waterproofing managing director
Warren Muschialli comments: “The experts at Stonehouse identified a litany of issues, from the weak, permeable structure to the
lack of continuous waterproofing between levels, the inadequate pumping system, the blocked cavity drain system, and the non- existent external deck waterproofing and drainage, amongst others.”
Once structural reinforcement had taken
place, Stonehouse proceeded by reinforcing dry pack joints with HydroSeal 313-WP and HydroSeal 103 2K, sealing voids and structural weaknesses with Newton Injection Resins, and preparing all internal surfaces before spraying HydroSeal 103 2K.

ADV.indd 1 Meet BS5250 with fewer tile vents – with Ubbink!
Ubbink’s UB19 Hooded Tile Vent and UB62 Inline Tile Vent each have the largest free vent areas available in their respective applications. So with Ubbink, fewer vents are needed for both high and low level ventilation, to meet BS525.
The UB19 is suitable for most roof fi nishes with pitches above 20º and has a free vent area of 22,000 mm2. The UB62 provides up to 15,000 mm2 of free vent area and is suitable for use with profi les including Modern, Ludlow Major, Double Roman, Double Pantile and Ludlow Plus on roof pitches above 25º. Both vents are available in a range of colours and can be supplied with adapters allowing conversion into soil/vent terminals or for use with mechanical and natural ventilation.

Roofing_DPR.indd 1 Months from Part L and still much to do
Changes to Part L of the Building Regulations – which sets the standards for the energy performance and carbon emissions of new and existing buildings – come into force in just a few months’ time. And, according to an exclusive survey of housebuilders, architects, and specifi ers conducted by Marley, almost two thirds of respondents are ‘unaware’ of the changes outlined in Part L. The survey found that for those that expressed knowledge of the new Part L regulations, ‘cost pressures,’ ‘a lack of skills to implement the changes’, and low levels of ‘client understanding around sustainability’ were viewed to be the biggest challenges. Questioned about confi dence levels associated with the changes and their resulting responsibilities, 79% admitted they ‘did not feel confi dent’ or were ‘unsure’ about their understanding of the new responsibilities ahead of the impending revisions. Just over one in ten (14%) agreed that they felt ‘confi dent’. Stuart Nicholson, roof systems director for Marley, comments: “It appears that awareness and subsequent confi dence around the impact of this important milestone among housebuilders, architects, and specifi ers is currently low.”

They then adhered insulation beneath
soffits, providing an integral vapour barrier, installed a full Newton CDM System with a dedicated
Titan-Pro sump chamber,
dual NP750 pumps and Victron battery backup protection. Finally, both decks were waterproofed with Newton’s liquid primers and membranes, overlaid and protected by a NewSeal 408 DeckDrain membrane.
