Kick Boards

On scaffolds, on building sites, kick boards are quite rightly mandatory. They prevent tools or materials being knocked off to fall on people working below. When bridges cross rivers this is not relevant When bridges cross other paths it is good practice but is not always observed. If the kick board is in direct contact with the deck it will trap debris. Soil will build up and plants establish. The combined effect will keep the wood permanently wet and the life of the timber will be reduced, On equestrian bridges The British Horse Society recommends high kick boards -&n...

Boardwalks are a blessing

As a measure to protect sensitive environments, prevent erosion and make it practical for members of the public to enjoy wild spaces, without feeling at risk, boardwalks are the solution. They can be used on the coast, in moorland, march, mountain or farmland. In some locations they are highly seductive and draw people away from the hubbub of life into wild and special places. They provide a proximity and intimacy with the environment without comparison. Less mobile people feel secure on them, provided they are correctly designed and are structurally sound. Small k...

Why are Kit Bridges so popular?

Building a kit bridge brings a community together. Shared memories and a sense ownership of the bridge appeals across the ages.   IKEA has taught us all how to follow instructions and each kit is supplied with detailed instructions. If there is any nervousness we can supply a Supervisor to either offer advice or to organize the job. Volunteer Groups can supply and install a bridge and make it affordable After the recent floods there are many site which need new bridges and the local authorities lack the funds to pay for them. Community Action is often the only alte...

Anti Slip Treatment

Bridge users regularly slip when surveying older bridges. It is only their agility which saves the day Leaf litter, algal growth, dog-mess and dampness can reduce untreated decks to an ice rink. Especially on hardwood decks. The introduction of grooving was a great help Clearly grooves are only effective if they are not over laid with litter, As anti slip treatments became available the question of the most effective use of it arose. In the first instance the material was spread across the entire surface and before it cured aggregate was sprinkled onto it. Handling t...

What is cladding on a bridge?

Occasionally we are asked to make a bridge with steel beams look like a timber one. It Surprises us how people feel galvanized steel finish is out of place in the countryside. virtually every field gate and kissing gate is galvanized. We don't have these feelings as Engineers. Ever eager to supply what our clients want, we naturally conceal the beams. This process is called cladding.   in order to inspect the bridge, the cladding needs to be capable of being removed. This can be a costly process involving scaffolds and the disturbance of wildlife (bats). B...

Why use Steel and Timber Bridges?

Our name is missleading!   We are on of the major suppliers of bridges with steel beams and timber deck and parapets. As the bridges get longer the use of timber beams becomes an issue.   The stiffness of the beam is achived, as the span increased, by incresing the depth of the beams and/or the thickness of the beams. The beams get huge and become hard for our kit bridge useres to manage on site. Our prefered installers mutter darkly when given bridges with huge beams. In softwood we run into 3 issues. Firstly:  The avaliablity of beaming in...

Wood

Two kinds of timber is commonly used by bridge engineers. Softwood and Hardwood. Softwood is more economical. It comes form Scandinavia and the Baltic States. It is farmed there on a massive scale and absorbes huge amounts of carbon.   The two most common species used are Douglas Fir and Redwood. Douglas Fir is stronger and has a natural preservative in it. Redwood is used for the parts which come into contact with the user as it planes up better than the Douglas Fir. All our softwood is stress grades C24 and it is all tanalised after machining to maximise its life....

No placeforplastics

It is simply wrong to delberately place plastics in the environment. Paticularly those places we need to keep un poluted. They will eventually break down and perneantly degrade our world. Some misguided people believe it is "green" to use recycled plastic instead of timber for access provision. We are actually using our special places as a store for waste plastic It uses lots of energy and more polymer to convert the waste into a "usable" form. In this form it is variable in quality and performance.  Laughably these recyced plastics are much more expensive...

Another satisfied Client!

After he laid the final deck board the volunteer Project Manager from a Cricket Club tap dances with delight. We love working with volunteer groups and have a long track record doing it.   Building bridges is a hugely satisfying group activity and builds memories which last forever.
