The last retaining walls are in

The SE corner (back left if you have your back to the sea) corner of the site has had the shuttering for the last section of retaining wall and the boundary wall finished this week:

The concrete has been poured into the shuttering.

Shuttering has been taken down (and not yet tidied up, that was later).

Above the retaining walls the site is levelled out for the section of the first floor that extends here.

More Glulam beams have been delivered.



Groundworks are almost done

The last site update I did was on the 20th of October, so almost 3 weeks ago !

The stainless steel elements of the frame had been delivered and the site had had it’s last big concrete pour, for the west side retaining wall. Great to have got to those retaining walls up an in place with no problems to the neighbouring property.

The rest of the frame, which is wooden Glulam beams, have arrived on site:

In the above photo, you can also see that the site is covered in a black poly sheet that is then gravel covered. There to prevent plants growing up under the house.

Before that was put down, the shuttering on the retaining walls was taken down and further footings have been poured. You can also see the start of the replacement wall between Silver Spray and Ramoth.

At the back (south) of the site, they are in the home straight putting up the last bits of retaining wall:

The small section of the west retaining wall, that is being built up with blockwork, is also almost done:

Steel delivery & the last big pour (of concrete)

Three, maybe four concrete truck arrive on Friday afternoon to fill in the top half of the back retaining wall, the hot tub slab and the footing for the wall to Ramoth.

Pre the concrete pour, post the last photos, the steel for the hot tub slab had been raised to increase the cover:

and the footing for the boundary wall extended:

The steel beams for the frame (some spans are too big for Glulam beams that wouldn’t become very thick) arrive:

2013-10-18 09.02.16_600w


On Friday afternoon the long concrete pump:

2013-10-18 14.29.55_600w


2013-10-18 09.02 (10)


was extending up to the upper retaining wall:

2013-10-18 14.37.04_600w

That by Saturday morning, was set solid enough to walk on:

2013-10-19 08.52.14_600w


You can also see the boundary wall footing on the right the hot tub slab:

2013-10-19 08.47.18_600w

More groundworks progress

The footing to put back a wall between Silver Spray and next door is dug.

2013-10-16 16.46.12_600w

The drainage sheet for the upper section of retaining wall concrete pour is in place.

2013-10-16 16.47.41-2_600w

The over sized (to future proof) hot tub area slab hole is dug out and re-enforced. The boundary wall behind this has also been taken down to be replaced with a wall with a proper footing.

Retaining wall concrete, wall smashing, small wall foundation

A lot went on today.

The big pile of earth and rock that was in the garage area, was cleared away in the morning.

The retaining wall and it’s foundation footing has been broken up a chunk.

3 truck loads of concrete have been pumped from the trucks to behind the retaining wall shuttering for the main house.

Three cement trucks arrive:

The truck parked in the garage area, just in from the cement lorry, is pumping the cement up the black pipe to the chaps pouring it in, and then vibrating it, so that it all settles down with no air gaps etc.

Looking at the area, that at the time of the photo hadn’t had concrete poured in, you can see the spacers to keep the steel bars a set distance in from what will be the external edges of the concrete.

You can see the picker on the digger, that is breaking apart the re-enforced wall and it’s foundation footing.

At the front, a small footing is being made to re-instate the Kiephuis garden:

Silver Spray to Ramoth wall

Nigel and Sam have started taking down the “rotting” dividing wall between Silver Spray and Ramoth. The agreed plan is to put in a small footing and a 2 to 3 block wall up for now. Once the Silver Spray building works are done, we can decided if we want this wall to go higher in any areas.

This has exposed that the Ramoth courtyard, which used to hold back the rear garden with a retaining wall has a bulging lump of concrete into the Silver Spray plot. The bulge looks to be about a foot into the plot, which would narrow the path down the side of the house too much to leave in place.









Retaining Walls :: 1 step back but at least 3 forward

At least it was spotted. The black RIW double drain (black bumpy sheet with front white anti silt up sheet) that was wrapped around the garage wall was part buried before it was noticed that it was the wrong way around. It needed to be black thick plastic side to the garage wall.

Incorrect way around:


So Nigel and Sam spent 1 to 2 days digging a trench down to the bottom, in order to take it up and put it back in the correct way around.



And then repeat back filled, compacting every 20mm of in-fill.


Sam and Nigel (the only 2 on site for a bit over a week) dug under the wall of the neighbours (Kiephius) wall to expose their mains water feed from the street stop valve. This is so that we can replace it with a modern Polypropylene water pipe before it is re-buried.


They have also started building a small retaining wall, backfilled with concrete to better support the ground under Kiephuis balcony. Their property structures are going to end up better supported than they were.



The link wall between the front NW corner of the garage to the Kiephuis front wall has been built.



On Monday the 7th of October, the site team jumped from 2 (Nigel & Sam) to 6. The pace picks up and the current position of being behind schedule looks set to be redressed.

The main house retaining wall shuttering is coated to help it not stick to the cement before it’s put in place.



The steel work has a 2nd layer put inside it, with cross links.

When this first goes up the cover (distance between the steel and the outer edge of where the concrete will exist, so the distance within the concrete the steel will end up) of the steel looks to be a problem, but spacers are put in, to hold it at least 30mm in from the external earth, wood or chippings.




The shuttering going up, with the remaining steel mesh put up against the wall in the garage and the rest of the site cleared (note the back left (SE) ramp dug back) makes the site suddenly big again.




That’s a lot of material that has been heaped into the garage area.





Retaining wall backfill with drainage

The bottom of the retaining wall for the house has had a land drain (perforated pipe), wrapped in geotextile membrane (black sheet material that prevent land drainage systems from clogging with silt and fines by creating a water permeable barrier preventing fines and silt passing but allowing free movement of water into the drainage channels) has been laid down and then covered with gravel.

The same has been done for the retaining wall for the garage, where the back of the wall, that has already had 2 coats of SBR waterproofing painted on, has had the RIW Double Drain sheet secured to the wall. This is so that water coming through the ground, drains down the wall, to the land drain and away, so as to not build up pressure on the wall.

Above is for the house retaining wall.
Below is for the garage retaining wall.




Every 20cm the compactor is run over to keep it all tightly packed in.



They have put some props up on the wall while they are working below this bank. Better safe than sorry.



In the photo below, you can see that some of the garage wall has had the top half filled with concrete.






Garage wall blocks get to their top

The blockwork garage wall is now at it’s max height.

There might be a layer of bricks on the top to bring it to the desired / planned end height.

That means the land behind, some of which is my neighbours garden, can be back filled and their garden re-instated.

The space that is the garage is going to be left open for the crane to lift the house panels in place.

Once that is done, the garage roof will go on. At the end the roof will be earth covered and grassed over.
