Yes this is possible but some precautions are needed. We recommend that the floorboards are narrower and thicker say 85-100mm wide by 19mm thick and these boards are laid over a 15mm plywood sheets over the concrete. The alternative is 21mm engineered wood product which can be laid directly onto the concrete. It is important to condition any solid wood flooring in this situation by fillet stacking it in the house with the heating running for a couple of weeks. We also recommend American White Oak, in either solid or engineered, which is a very stable timber and performs well in these situations.
We recommend the slab is tested with hygrometer, to measure the moisture vapour being emitted at the outset. In our installations we use Selleys liquid-nails vapour-barrier system (VBS). This is a two pot solvent based product which is painted on. Once the VBS is dried we would re-test to determine if the moisture level is within pre-determined BRANZ standards. It may be that one or more additional coats is needed to achieve the required barrier. Assuming the VBS barrier is not accidently pierced then the VBS should permanently block water coming up from the slab. A word of warning – you should not automatically assume an old concrete slab is dry. We have moisture tested slabs which have been down for 20-30 years and they still needed a coating of VBS to bring them into specification for laying a wooden floor.
Yes, in the first instance we would check our stock to see if we have matching boards. If not, we can custom profile to match in the same timbers. All we need is a short sample sent by courier or dropped in at our premises. We do charge a modest machine set up fee in these instances as we stop normal production and reset our profiler to the exact specifications.
Purchasing recycled timber is the best sustainable option as the timber is being re-purposed or reused. In the main, any recycled timber is completely sound but it is often the buildings which are at the end of their functional life and are being redeveloped e.g. for earthquake strengthening or the site is destined for another use. Most of our timber options are sustainable. We only buy in New Zealand native timber which has been sustainably harvested under Ministry of Primary Industries (MPI) licenced forestry management plans. Sustainable options for imported hardwoods are generally overseen by companies operating under the umbrella of the Forestry Stewardship Council (FSC) www.fsc.org or Programme for the endorsement of Forest certification schemes (PEFC) www.pefc.org.
We are based in Upper Hutt so can travel easily anywhere in the Wellington region, Wairarapa, Manawatu and Taranaki. We have completed floors in homes in Taupo, Bay of Plenty and Coromandel. We are happy to complete larger projects further afield including the South Island.
There is no one standard size in parquet. We have access to many species of timber and have the capacity to custom profile parquet pieces in any size.
There are no issues with installing wooden floors in bathrooms or kitchen providing a good quality polyurethane is used to seal out any spilt moisture.
This depends on the amount, sizes and timber species chosen. We usually have good stocks of recycled timber and uplifted flooring. Assuming we have the boards in stock then 1-4 days to prepare the order is normal. Larger orders and custom runs may take 1-2 weeks to organise. New timber can be ordered in and again depending on species, timing is normally around 2-4 weeks. Engineered flooring is normally available within a few days. We will do our best accommodate special orders and can re-prioritise our workshop production if necessary.
We can organise delivery of all orders. We use standard couriers for overnight delivery on small orders, a builder’s courier or our own truck for deliveries in the Wellington region and mainline transport companies for New Zealand wide deliveries. Freight for delivery to Auckland of upper North Island is surprisingly cost effective because of freight companies back loading to the ports in Auckland and Tauranga.
We recommend Rubio Monocoat oils as being superior to polyurethane, and easy to maintain. Rubio Monocoat oils contain no VOCs. Water based polyurethanes are also good option. They are hard wearing and do not emit the strong solvent smell of moisture cured (aka solvent-based) polyurethane. This means a home owner can usually stay overnight in their home, assuming they have access to another part of the house and without crossing the floor being sanded and coated.
