April Blog

During April Glenco was occupied reconstructing an old garage area at Millers Court in Chiswick.
The works entailed excavation and replacing the sub base with an Mot type 3 sub base to levels and falls. Falls were enhanced with crossfalls to a new linear drainage system with a 25 tonne loading cast iron grating. Great attention was paid to ensuring adequate falls from the garages to the channel to ensure the garages would never flood!

The job was made more interesting by bands of Blockley clay paving bricks installed flush with the macadam surface course. The paving bricks formed an edging detail and also decorative bands through the entrance drive section. Pavers were laid on a concrete bed to levels and falls.

A new 12:1 semidry leanmix was installed as a base for the new surface and a 6mm Stone Mastic Asphalt Tuffdrive proprietary surface course with polymodified binders laid as the surface course.
As with any garage area static turning is often an issue during the summer when the new surface has been installed – the polymodified binders a re specifically designed to mitigate this issue as much as possible. As always we have endeavored to bring quality to the surface!

March Blog – Reconstructing an old Garage Area

We had a tricky little job to undertake in an expensive riverside courtyard development, the brief was to reconstruct the garage area without inconvenience to the residents in the block. The tarmac had been installed in the seventies and had oxidized and crumbled into the sub base, in addition there was some tree root damage from trees that had subsequently been removed.

We used a 3 tonne excavator and a 1 tonne dumper to excavate and remove the decayed material and the areas around the old trees. Material was carefully transported to a designated area, neatly boarded, next to the entrance – where it could be safely removed by grab lorry. The sub base was reconsolidated and amended with an Mot type 3 high stone content sub base to correct levels and falls. The central drain gulley was adjusted to increased the crossfall from the garages and a new C250 25 tonne loading cast iron grating installed on concrete. To the existing planter areas, we used a Marshalls KL kerb in charcoal to form planters using a chamfered profile with internal and external radius pieces to form the corners to the planter detail, giving a nice structure to the planter areas.

We chose to use a 12:1 semi dry lean mix concrete instead of the conventional dense bituminous macadam base course. The lean mix concrete is laid and compacted in the same way as the macadam base course but tends to give a more solid base construction where the whole sub base structure has not been reconstructed from the subgrade up. The lean mix base is a useful addition to the armory when considering the best available options to reconstruct legacy areas where the budget constraints may preclude full depth reconstruction.

Once the lean mix had cured we were able to install a 6mm stone mastic asphalt ‘Tuffdrive’ proprietary surface course, with a bitumen emulsion tack coat applied to the lean mix base. The Tuffdrive performs excellently where there is likely to be static turning in confined areas. Aesthetically the Tuffdrive has a close graded appearance identical to conventional dense bituminous macadams, but is two grades higher in bitumen content and the polymodified binders sets the material off very hard as soon as the materials have cooled from laying temperatures.
Using this format Glenco were able to bring Quality to the Surface as we always strive to do!

Drive and Forecourt Challenge

Late February saw an interesting challenge for the Glenco team.

The Bridge Farm Nurseries required a new section of access drive and forecourt in front of their offices and holding area. Apart from the worn and broken surface -there were no falls to clear the surface water and the existing surface was holding water after rain in multiple locations.

We took 50 spot levels with our laser and made a careful plan of the area. We calculated that if certain areas were planed down, including a concrete section of the existing forecourt, a small cross fall could be created to clear a section of the access drive to some existing drainage. We used a half metre planer, with a lorry to clear planings and a mechanical sweeper to clean the area. With the surface planed down and the crossfall achieved we enhanced the available falls with 6 tonnes of regulating before the allocated day to install the new hardwearing surface. Due to the extremely heavy anticipated usage of the surface with 8 wheeled 32 tonne delivery lorries, forklifts manoeuvring on the surface a heavy traffic from the rear holding area – we used a 10mm Stone Mastic Asphalt 40-45mm thick with polymodified binders to cope with the anticipated usage. The finished result made quite a transformation to the area which was aesthetically important for the shop entrance and the functionality of the new surface essential for the access drive to the main areas at the rear of the facility.

Quality was brought to the surface!

January Blog

Glenco has been busy during January working at Lasham Aerodrome. As the aerodrome was constructed in the 1940’s much of the infrastructure is beginning to decay or is in need of replacement. This is very much the situation with the tarmac, much of which is heavily oxidized and is breaking up. There has been some historical subsidence in some areas of the surface causing depressions that result in large puddles after rainfall. The presence of standing water on the surface has accelerated the decay to these areas. The heavy and demanding usage at the aerodrome with large vehicles, plane tugs and the large 737’s require the tarmac to be in good condition and well constructed in order to take the weight and manoeuvring of these vehicles.

Problem areas of the runway and the perimeter access road have been identified and allocated for replacement. We have used a bobcat planer and sweeper attachment to plane down and prepare the specified areas, areas have been regulated to bring them to within surface course tolerance. Once areas regulated, thoroughly compacted and prepared, a new surface course 10mm Tuffdrive SMA HS PMB proprietary surface course with plolymodified binders laid and compacted flush to all adjoining levels. A hardstone granite aggregate is used in the surface course to ensure appropriate skid resistance to the surface when trafficked. A hot pour joint sealant is used to seal the joints to all the reconstructed areas to prevent any water ingress to the new structure.

Due to the continued access requirements during the works, we needed to close sections of the access road but still allowing traffic to pass so traffic management was an important consideration.
Whereas it is always easier to prepare larger areas at one time and reconstruct them accordingly, this luxury was not afforded to us! We needed to prepare a few sections and replace the tarmac on these areas opening up sections again for normal usage. It has been more time consuming to have to work in this manner but it has caused minimal inconvenience to 2 Excel Engineering who manage the airport, so they are very pleased with the way the programme of reconstruction has been run. The functionality and the appearance of the hard surfaces have been greatly enhanced without any impairment to their operational capacity.

An interesting and involved challenge, but nevertheless, Glenco has again brought Quality to the Surface!

December Blog

December has seen Glenco busy working on industrial estates and commercial areas, repairing and reinstating heavy duty drainage channels, concrete reinstatements and tarmac repairs. The heavy duty drainage channels used on the Ridgeway Trading Estate in Iver were no longer available in the UK, being made by Stora who only had European outlets available for supply. The importance of matching drainage runs with the same sized channels is obviously imperative. We tracked down a supplier in the Irish Republic who were able to ship us the required channel without much lead time, allowing for a seamless installation.

The macadam structures in heavily trafficked areas require the strongest compacted courses to support the type of vehicles using them. We have installed 20-32mm dense bituminous road base macadam at 80-90mm depth. The surface course, which require the strongest available materials, we have used a 10mm Stone Mastic Asphalt SMA with polymodified binders. This type of surface course is designed to cure very rapidly and to resist slow and static turning by heavy commercial vehicles, making it ideal for the anticipated usage. Edges are then sealed with hot bitumen sealant to prevent water ingress to the reinstatements, thus enhancing the longevity of the repair.

As with all Glenco repairs, such attention to detail, will always ensure that ‘Quality is brought to the surface’!
