Trace win awards for top marks in industry examinations three years in a row. ‘Our Top Candidate Ever’

Just had an email, as below, advising that David Hockey gained the highest EVER marks of any candidate in winning both the 2010-2011 examination award for CSSW for waterproofing design, already having won the award for CSRT, the examination for damp and rot in 2009-2010, this following James Hockey winning the same in 2008-2009.

27th February 2011

Dear George
David is to be congratulated to win both CSRT and CSSW awards. Our top candidate ever!
Very pleased that James and David will be attending the AGM and awards ceremony. We should try to be better behaved than we were last year and ensure that we go home with the right jackets!

Kind regards

So much for rising damp, so much for woodworm !

By George Hockey

So much for rising damp!

Upon completing a remedial basement waterproofing contract in Highgate where liquid applied bitumen tanking had seriously failed (case study will be forthcoming on our web site), a neighbour requested a survey for basement conversion in her 1930’s property.

In discussing the project after inspection, the lady householder asked whether we undertook damp proofing and woodworm treatment, this because I mentioned that some evidence of woodworm was seen in a lintel within the basement, but that it showed no sign of recent activity.

The little brother done good (AGAIN) – David Hockey wins CSSW Award for 2010.

As a son joining the family business, it’s not easy finding ways to stand apart from your MD/Father, when he’s been such an exponent of the industry since starting the firm in 1974.

One such way is to do well in your exams, and as such I managed to win the CSRT (certificated surveyor in remedial treatments (damp, timber, wood boring insects) back in 2007, which is awarded to the highest schieving candidate in a given year.

Nice photos, corrosion and expansion of early 1900′s flat bar fish-tail wall ties.

Yes we are Trace Basement Systems, but you can also call us Trace Remedial Building Services, under which moniker we have remedied general problems of dampness in buildings since 1974, this including wall-ties.

David & Dave

Our David Hockey, who in addition to holding the industry CSSW and CSRT qualifications, is an MRICS Chartered Building Surveyor, is doing a survey on a church in Birmingham today for Dave Tomlinson of Checkley & Co. http://www.checkleys.co.uk/, a practice of surveyors who took him on for a week when on school work experience, with Dave putting him up at his own house at that time, which must have been about sixteen years ago. My thanks Dave, George.

Clients that get it.

Example flooded cellar due to tanking failure

What can happen when you don't get it right - tanking failure.

When dealing with waterproofing and basement design, there are typically options in respect of the methods or ‘types’ of system that could be selected, with the objective of creating a dry basement which stays dry in the long term.

Different systems provide different levels of protection/risk and so what we are always interested in, is the lowest risk system.  This is because we provide guarantees on the systems that we install, and so would not survive in business for very long if we employed risky systems which required us to go back, and back and back, and believe me this happens to others, which perhaps explain why there are so many basement conversion/basement design companies which start up and then seemingly dissappear year after year (another blog post in itself)! 

So, we have to justify and explain our basement design choices to the clients and professionals involved in a given scheme, which we do time and time again, however it’s fantastic when a client just gets it, as experienced on an inspection yesterday.  

This chap had little in the way of construction knowledge, but securely grasped the principles explained to him in respect of why we do what we do.  He will get a dry basement. 

Although this should always be the case where a detailed explanation is given, we in some cases have to deal with preconceived notions of what ‘waterproofing’ is right for a given basement scheme, and it can be that the more an individual knows about construction, the more they believe they know about basement waterproofing, and the less willing they are to accept alternative ideas, even when this means a much more detailed and rationalised basement design process, versus simply choosing a product and shoehorning it into a given site and structure. 

The assumption that basement waterproofing design is a simple matter results in what must be millions of pounds of headache and remedial work each year, which the new BS8102 design guide (the UK waterproofing bible) deals with by repeatedly advising that waterproofing specialists (like Trace) should be involved in a project at the earliest stages.  

Looking back to my younger years, whenever I believed I knew it all, it wasn’t typically long until I was shown that I did not.  The lesson is, that an open mind is a vehicle for learning, and that where basement waterproofing is concerned, you do not want to learn this the hard way. 

…and furthermore, listen to the advice provided by those that will have to honour the guarantee, rather than those who simply profit whether it works or not (another blog post to write!).  Also see: http://blog.tracebasementsystems.co.uk/guarantees-not-worth-the-paper-they-are-printed-on

FAILING SPORTS FLOORS

 

We seem to be dealing with several sports floors where water and water vapour have caused problems at the moment, one in a hotel where we are being limited to part protection of the area via WaterGuard drainage channels, a sump and cavity drainage dpm, one in a school being extended where the heating was turned off for a time, with it not yet known whether the lack of heating or adjoning newbuild has tipped the balance to cause the hardwood to warp, and one, the worst, being in another hotel where relatively new hardwood overlaying an older floor had badly warped and where the odours in the air markedly indicated that fungus was present.

The sad fact was that the client had paid out good money to a specialist sports floor installer, including a sum to deal with any problems with the existing floor below. The work was completed and some time afterwards the warping commenced, following which I was called in. The whole place and I am actually speaking of two sports floors, one a squash court and one an all purposes court, actually reeked of damp and fungus and limited opening up of the floors at the edges showed clear evidence of rot in older timber below the new, along with wet rot fungus that had started to spread up the walls and into low level joinery where present.

The installer of the hardwood floorboards had returned and taken up the edge boards so that the boards could move and settle back down and had apparently advised that once the boards had settled back down, they could make good. Some hope that was.

I instead advised the client that they either remove sufficient hardwood boards to facilitate inspection below before deciding on the way ahead, or to remove them all on the basis that ideally they needed to be stored elsewhere in a dry environment before being pt back after whatever other remedial steps were required.

Once the client’s building contractor commenced removing the hardwood they soon found that the original floors below were in extremely poor condition and you can see in the photos here that the best place for the older floorboards was in the skip. I inspected again after the boards were removed and found that most of the floor joists were decaying, that a great amount of old wood had beed discarded on the oversite below, much of which seemed to date from prior to the newer hardwood being laid and that both wet rot and dry rot was growing on and out from such timber in many areas.

This is a sad case because the client is left with a great deal of cost to correct the problem, which is going to involve measures in respect of providing a fungus free dry void below the two floors, complete new floor joists and fitting back of the now removed hardwood, along with other damp related works, with the responsible flooring contractor not having been responsible in the first place and now refuting all liability.

They, the specialist flooring contractor, basically either misunderstood what they were doing by covering over old timber over a damp sub-floor void where timber had been discarded, with what amounted to a vapour limiting specification, thus changing the equillibrium, or they they did not care.
